SS Spring front hangar problem!!

[70sixpkrt]

I went to change my old springs to my SS springs and found out that my front spring hangar studs are not wide enough to fit the body.

   Im curious also. I thought about buying a set..

[70sixpkrt]

I believe the part # on the box said P4120079. I am wondering if they put they wrong part in the wrong box.

[charger Downunder]

Looks like you got the wrong one there ,they should be longer than standard to make up for the shorter spring,In the pic i cant see what lengh you have.

[70sixpkrt]

I think someone put the wrong part in the wrong box.

[70sixpkrt]

Well I just talked to Mancini Racing and apparently good ole Ma MP made a bach of wrong front spring hangars and it looks like I got one of them.   I just called Sumitt Racing and put in an order.

Sorry to see that happen Ricky.....major pain in the AZZ ! 

It's not just Mopar who screws up though. My buddy purchased a flexplate from Summit and it was boxed incorrectly with the correct part number stamped  into the part, figure that one out ! 

He ordered an 8 bolt flange flexplate and it came in the correct packaging and it had the 8 bolt pn stamped into it. Only problem was that it was a 6-bolt flexplate and won't bolt up to his crank.    We exchanged it this w/e right at Summit In Ohio on our way home from Pinks and even they were surprised to see such a blatant mistake. Unfortunatey $hit happens.....

Ps. Just a note ; when I installed mine (SS springs) in the upper hole the pinion was pointed up at the floorpan which was obviously way wrong. I ended up moving the front eye to the lower hole and all was well. Just a heads up bud

Ron thanks for the tip. Are you using a pinion snubber with your ss springs?

Ricky, my Dana is a custom built piece out of a truck so there's no mounting pad for the snubber. Most guys just delete the snubber when running SS springs because they are ineffective anyway....lots of rear end rise when the car launches. 


Ron

Thanks Ron. I was told to remove the snubber. Does your car sit high since you are using the lower bolt hole?

[mally69]

Please correct me if I am wrong, but when using the SS springs, the a$$ end goes up in the air becuase the springs  are forcing the rear wheels down harder on the ground correct?? I have seen them being used at the track before and that is kinda what it looks like they are doing.

[70sixpkrt]

The SS springs plant the tires to the ground for more traction.

[firefighter3931]

Thanks Ron. I was told to remove the snubber. Does your car sit high since you are using the lower bolt hole?

Yep, it's up there.    Right now there's no drivetrain or interior in the car so i'm sure it will drop down once more weight is added to the car. The SS springs also "settle" after a few street miles.

Hi Ron. I just installed everything and checked my pinion angle. I am using the top hole on the front hangars. Checking from the bottom of the rear end, it shows 4* nose UP. I also checked it from the rear pinion yoke and it shows 4* nose UP. Do I have to use the bottom hole like you did? Should it be 5*-7* nose DOWN? If so, how do I lower the front spring? Do I have to loosen U bolts and everything?  Did you have to use shims? Thanks . Ricky

Ricky, before you do anything measure the angle on your transmission....if it is 4* nose down that will offset the 4* nose up at the axle pinion then all you need to do is add some shims. The 5-7* nose down is a "race" setup....like i said in the PM 2* would be my choice for a street car that occassionally see's the strip. You can allways add clamps to the front segments of the leafsprings if you start to experience axle wrap-up 



Ron

[70sixpkrt]

Ron I checked the angle on the bottom of the trans. and it is 0*. I pulled both leaf springs off and lowered it to the bottom hole. I also added a 3* shim. The pinion angle now is 1* nose down. I took it for a ride and launched it. It felt good. No vibrations on the street or freeway. I think I will keep it like this because it is a street car. Dr. Diff said he does not like to see street cars with more than 3* nose down. It did pick up the rear alittle and not too bad looking either. Ron what do you think and thank you very much for your help!!!!

[firefighter3931]

I think it looks great Ricky ! 

Good to hear there are no vibrations in the driveline....that's what i expected you to report with a slight nose down angle. The SS springs are quite stiff on the shorter 20in (vs 22in stock) front segment and in most cases do an excellent job in controlling axle windup. You'll know better once you get it to the track but cross that bridge when you come to it.

Ron, do you think I should leave it like it is or try to find a 4* or 5* shim? I don't think the stud has enough room to add a 2* shim.

[firefighter3931]

I would leave it as is....it's working fine so far, why change it unless there is a problem ?

Thanks Ron. I knew you would have the answer!!

[firefighter3931]

Thanks Ron. I knew you would have the answer!!

You're welcome Ricky 

Just to elaborate on my reasoning : lots of guys like the 5-7* nose down but that's primarily a race deal. It works OK during hard acceleration with violent transbrake launches and engines making BIG power, but that abnormal pinion angle during normal driving conditions will accelerate u-joint wear and in some cases create vibration issues. The idea is to have a zero offset most of the time the car is in motion....for you that means "street" and not strip. 

You allways have the opportunity to clamp the front segments and/or add shims if need be.....but for the way you drive this car 99% of the time it will work fine, inmo. There's no point in setting it up for the 1% or less that you will race.

I totally understand. Once again, thanks for your help!!!

The stock front hangars are idiot proof by having an offset stud.  For those who have installed the SS springs, did MP copy this arrangement, or did they cheap out and make just one front hangar without the offset stud and he got the right parts?

[70sixpkrt]

I was told by Mancini Racing that Mopar Perf. made a wrong batch of front hangars with no offset. They were getting returns also. I ordered a set from Sumitt racing and there were correct with the offset.
